DOOR-OPERATING MECHANISM.

Specification of Letters Patent.

'l'atentcd Nov. 1.4. 1916.

Application filed February 14, 1918. Serial No. 78,152.

721 all whom it m or concern c it known that I, SAMUEL W. RAYMOND, acitizen of the United Statcs of America, residing at Adrian, in thecounty of Lencwec and State of Michigan, have invented certain new andusefullmprovements in Door- Operating Mechanism, of which the followmgis :1 specification, reference being had therein to the accompanyingdrawings.

This invention relates to an opemng and closing mechanism for doors,gates or other closures hinged or hung to swing in a horizontal planeand close a doorway or other opening.

' The mechanism to be hereinafter described in detail has beenespecially designed for opcninghnd closing the doors of garages,

carriage and other vehicle houses, and its use necessitates a positionwhich will. not interfere with the passage of an automobile in and outof the garage.

The primary object of my invention is to provide an opening and closingmechanism for doors that may be operated at a Point remote from thedoors and associated with the opening and closing mechanism is a latchor locking device for holding the doors normally closed, but operable insynchronism with the mechanism, whereby the doors can he expeditiouslyopened or closed.

Another object of my invention is to provide an opening and closingmechanism for doors which permit of one door being moved in advance ofanother door, whereby doors having chamfered or mortised meeting edges Imay be properly closed.

Another object of my invention is to pr vide a novel mechanism foropening and closing sliding or rolling doors, the mechanism including aseries of articulated levers that can be easily installed at the upperedges of the sliding doors to shift the same when desired.

A still further object of my invention is to provide a simple, durableand inexpensivc door opening and closing mechanism that can be easilyinstalled in a garage, in an overhead position, to open and'elose thedoors by a single operation, which otherwise would consume some time.

- The above and other objects are attained b a mechanical constructionillustrated in tlie accompanying drawings, wherein Figure 1 is a, planof the opening and closing mechanism in connection with a set of doorswhich are closed, the mechanism being partly broken away; Fig. 2 is asimilar view of the mechanism showing the doors in an opeirposltion;Fig. 3 is an elevation of the opening and closing mechanism showing thedoors operated thereby in a closed position;

:g. 4 IS a plan of a door opening and closmg mechanism illustrating aslight modification of my invention, and showing hinged doors in aclosed position; Fig. 5 is n simi- ,flaryiew of the same constructionshowing the doors in an open position; and Figs. 1'; and 7 are detailviews of brackets.

As an example of an installation of the door opening and closingmechanism, there is shown a wall 1 having a dmrwuy adapt ed to be closedby a set of hinged doors 3 and 4.

Connected to the well 1, above the door way 2, is a skeleton bracket 5providi two bearings 6 having a fixed relation relative to the wall 1and supported in substantially the some horizontal plane as the upperedges of the doors 3 and 4. Pivotally connected to the bearings 6 aremembers 7 and the outer ends of said members are pivotally connected, bybrackets 8, to the upper edges of the doors 3 and 4, adjacent the hingededges thereof.

The confronting ends of the members 7 are pivotally connected by links 9to the end of a lever 10 fulcrumed u on a three leg or spider bracket 11secure to the well 1 at one side of the skeleton bracket 5. The lever 10extends to one side of the doorway 2 and the end lever has a pin 12extending luto the slotted end 13 of 'an operating rod 14, and byreciprocating this rod the lever 10 may be rocked upon its fulcrum andthe members 7 actuated to open or close the doors 3 and d. The upperedge of the doorway 2, at'the inner side of the wall 1, has a keeper 15adapted to receive a latch 16 slidable in a guide or casing 17 connectedto the upper edge of the door 3. The latch 16 is actuated by aspring'hcld pivoted arm 18, carried by the door 3 and said arm is'connccted to a cable 19, connected to the slotted end 13 of the rod 14.The cable 19 represents a suitable flexible connection between the arm18 and the rod 14 and said cable is trained over a sheave 20 and througha guide 21,

and l to an open position. There is sufficient slack in the cable 19 toallow 1: e

latch 16 to snap into the keeper 15 when the doors 3 and 4 are closed,and it is appar out that the rod 14 may extend to any desired locationfrom which it is desired to operate the doors.

'With the brackets 5 and 11 made of skeleton or spider form, the greaterpart oLthe mechanism can be made of light durable structural steel andcomparatively few parts are required, consequently the wall 1 is notsubjected to any stresses or strain by reasonof the Weight of theopening an closin mechanism.

In 4 igs. 4 to 7 inclusive there is illustrated.

- a. modified form oi". door opening and closing way,

' ward the wall .ferred form of construction.

' connection with t hinged doors are designated 30 and 31. Above thedoorway are braclo ets 353 pivotally supporting bearings 33 for members34, and said members are pivotally connected to brackets 35 of the doors30 and 31. The members are also pivotally connected to links 36 andthese links extend toabove the doors 30 and 31, in

to the links 9 of the pre- The links 36 are pivotally connected to alever 37 fulcrumed upon a one arm bracket 38 extend ing outwardly fromthe wall above the doors 30 and 31. An 0 crating rod 39 is used in lielever 37 and said operating rod is adapted to actuatea latch mechanismin conjunction with the door 31.

What I claim is 1. In a. door opening and closing mechanism, thecombination with a wall having a doorway, and a set of hinged doorsnormally closing said doorway, of brackets carried by the inner side ofsaid 'inembers pivoted on two of mechanism. The

contradistinction wall above said door said brackets and pivotallyconnected to the up said lever to said per edges of said doors adjacentthe hinged edges thereof, a lever iulcrumed on the other of saidbrackets, links connecting one end of members, and an operating rodconnected to the opposite end of said lever.

2. In a door opening and closlng mechanism, .the combination with a wallhaving a doorway and a set of hinged doors normally closing saiddoorway, of brackets carried by the innerside of said wall above saiddoo rway, members pivoted on two of said brackets and pivotallyconnected to the uper edges of said doors adjacent the hinged edgesthereof, a lever fulcrgumed on the other of said brackets, and havingone end thereof connected to said members, an operating rod having aslotted end connected to the opposite end of said lever, and a latchadapted to hold. said doors closed and connected to the slotted end ofsaid operating rod to be operated in advance of the mechanism whenopening said doors.

3. In a door opening and closing mechanism, the combination with a wallhaving a doorway and a set of hinged doors normally closing; saiddoorway, of brackets carried by the inner side of said wall above saiddoorway, bearings carried by two of said brackets, a member pivoted oneach bearing and pivotally connected to the upper edge of a dooradjacent the hinged edge thereof, a lever fulcrumed on the other of saidbrackets and havingan end thereof connected to said members, and meansto facilitate operating said lever at a remote point relative to saiddoors.

4. In a. door opening and closing mechanism, the combination with a wallhaving a. doorway, and a set of doors normally closing said doorway, ofbearings supported from said well above said doorway, memhers supportedby said bearings and connected to the upper edges of said doors, afulcrumed operating lever supported from said wall and connected to saidmembers whereby said bell cranks can be simultane-' and closingmechainner side of said wall above said doorway.

members pi'votally supported from two of said brackets and pivotallyconnected to the upper edges of said doors, a lever fulcrumed on theother of said brackets, links connectin}: one end of saidlever to saidmembers. and means engaging the opposite end of said lever adapted formoving said lever to open and close said doors.

In testimony whereof I afiix my signature in presence of two witnesses.
